The electronegativity generally increases as you go from left to right across the periodic table. It decreases as you go down the periodic table. I think you can see that the reason for this is going to depend on those same factors that we used to explain the trends in atomic size, ionization energy…

The ionization energy measures how hard it is to lose or remove an electron. High ionization energy means that it is hard to lose electrons. Low ionization energy means that it easy to lose electrons.

Energy is from Greek energeia "activity, operation," from energos "active, effective," from en "in" plus ergon "work." Specialized senses of the word energy include the power that comes from sources such as heat or electricity, and the ability of sources such as heat or light to do work. In physics, an erg is the centimeter-gram-second unit used to measure the amount of energy or the amount of.

These naturally occurring atoms require a low amount of energy to donate an electron. However, donating more than one electron requires a prohibitively high amount of energy. Khanna and colleagues.

Electron affinity: the energy change when a neutral.
